Study finds huge differences in size and shape between Chinese and Caucasian brains:

>Global volumetric measures were used to identify significant group differences in the brain length, width, height and AC-PC line distance. Using the LONI BrainParser, 56 brain structures were automatically labeled and analyzed for all subjects.
>Genetics and environmental factors make the Oriental and Occidental populations dissimilar. Thus, using Caucasian atlases for Chinese populations leads to overall brain volume, shape and size differences. Additionally, differences in brain structures between these populations may underlie different brain functions. If a Caucasian template is used in functional studies involving Chinese subjects, such genotypic and phenotypic differences may cause inaccurate measurements, comparisons and interpretations of results.
>The ethnic differences between the two populations are clearly visible–the Chinese_56 template (constructed using Chinese population) is relatively shorter but wider compared to the widely-used ICBM152 brain atlas (based on Caucasian brains)."

Study compares Asian brain volumes, finds that Chinese have 6% larger brains by volume than Indians, 2.5% larger than Malaysians:

This study associates various genes to brain volume, and then finds the proportion of those genes in the various racial groups. Although they are hiding their data on brain volumes. Almost none of the genes associated with brain volume are the same between populations.
